x = 3 -  \sqrt{8}    \\  \longrightarrow \:  {x}^{2} =  {(3 -  \sqrt{8}})^{2}  \bold{[square \: both \: side]} \\ \longrightarrow {x}^{2}  + 1 =  {(3 -  \sqrt{8)} }^{2}  +  {1}^{2} \:  \bold{[adding \:  {1}^{2}   \: both \: side]} \\ \longrightarrow {x}^{2}  + 1 =( 9 + 8  - 2 \times 3 \times  \sqrt{8})  + 1 \\  \longrightarrow {x}^{2}  + 1 = 18 - 6 \sqrt{8}  \\  \longrightarrow  \frac{ {x}^{2} + 1 }{x}  =6 \bold{[multiply  \: \frac{1}{x} \: both \: side ]}   \\ </p><p></p><p></p><p></p><p>\bold {\bold{\boxed {\boxed{///MARK \:  IT  \: BRAINLIEST///}}}}
